Made of nearly indestructible Zytel, these finely made magazine bumpers are designed to enable your factory magazines to load one extra round. Even more importantly to most shooters, they also help with seating magazines securely into the pistol frame by providing extra material to "bump" them into a locked state. Included with every bumper is an optional-to-install Spring Assist for even faster magazine ejection and assured magazine drop when the mag release is pressed. From competition shooters to casual backyard plinkers, everyone can benefit with these simple to install upgrades. Don't load less ammo, load more with the TANDEMKROSS Plus1 PRO magazine bumpers!
